Application filed February 7, 1928.

Serial N0. 252,533.

This invention relates to splice-clips for faces and alternately in opposite directions,

edgc-to-edge adjoining boards of the kind employed in the forn'iation of walls and ceilings of buildings and other structures and its principal object is to provide a clip of bendable sheet-metal which by a simple manipulation may be applied to firmly and securely fasten edge-to-edge adjacent wallor ceilingboards in permanent alinement and against relative displacement.

(ilther objects of the invention reside in details of construction as wrill be clearly described in the course of the following description, with reference to the accompanying drawings.

In the drawings, in the several views of which like parts are similarly designated,

Figure l represents a perspective view of the splice-clip;

Figure 2, a partially broken face-view of two adjoining wallor ceiling-boards fastened together by one of the clips; and

Figure il, a section taken on the line 3 3, Figure 2.

'lhe splice-clip as shown 'in Figure 1, is made of a single preferably rectangular piece 5 of sheet-metal scored at its opposite longitudinal edges by parallel relatively transverse slits 6 and '7 for the forimition of two series of tongues 8 and 9.

rIhe tongues S at one edge of the piece are bent at right angles to the body portion of the same, alternately in opposite directions, and the tongues 9 at the opposite edge of the piece are defined by transverse bending lines lll at the ends of the dividing slits 7.

The bending lines may or may not be used. If they are they may be formed by rows of perforations as shown in the drawings, or by otherwise weakening the metal of which the clip made.

,Figures 2 and 3 illustrate the method of applying the clip to two pieces of Wallor ceiling-boarifl l2 adjoining one another in a common plane.

The body of the clip is inserted between the adjoining edges of the boards, preferably from their sides opposite to their finished surfaces, until their ltongues 8 engage the sides of the boards.

The tongues 9 projecting at right angles to the finished surfaces of the board are now bent along their bending lines upon said surthereby securing the boards against relative lateral displacement.

After the tongues havebecn bent, they are forcibl y driven into the surfaces of the boards with a hammer or other suitable means. This draws the boards tightly against the tongues 8 on the opposite sides of the boards and thereby fastcns the boards in place.

In order to obtain this result, the distance between the bending lines and the edge of the body-member ot the clip at which the angularly bent tongues 8 are formed, is slightly less than the average thickness of wall,- or ceiling-boards, and by pressing the tongues 9 into the material of the boards, flush with `the tinished surfaces of the same, the clips may be completely concealed by the fillers of iilling strips or other .material commonly nsed in surfacing or linishing walls and ceilings.

lt will be apparent that the splice-pieces formed, and applied as shown and described, provide a normally invisible means to rigidly secure aiiljoining pieces of wallor ceilingboard in perfect alinement by an extremely simple iperation and at a very small. expense of material.

The splice-clip may be made of any bendable metal and coated `with a rust-proof substance, if so desired, and minor det ils of construction may be resorti-id to within the scope of the invention.

l-l'avin thus described my invention what I claim and desire to secure by Letters Ia tent 1s:

I. A splice-clip for walland ceilingboards comprising a metal piece having at an .edge thereof tongues bent at an angle and in opposite directions, and having at its opposite edge bendable tongues formed by tli'ansverse slits and weakened bending lines adjacent the ends thereof.

2. A splice-clip for walland ceilingboards comprising a metal piece having at opposite edges, bendable tongues formed by slits transverse to said edges, the tongues at one of the edges being further dened by weakened bending lines adjacent the ends of the slits.

In testimony whereof I have affixed. my

signature.
